Method for erecting a facility for producing electrical energy from wind

ABSTRACT

A method for erecting a facility for producing electrical energy from wind has the steps of preparing a site to receive the facility, including constructing foundations, and erecting an initial core tower panel and initial peripheral tower sections on their respective foundations. Work platforms and temporary guys are installed so that another core tower panel and other peripheral tower sections may be installed on top of the existing tower sections. The work platforms may then be raised, so that the process may be repeated. Shroud sectors are assembled as needed to form shrouds.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to power generation devices, and more particularly to a method of erecting a wind power generation facility.

2. Description of Related Art

There is no practical means in the prior art for erecting multiple large modules comprising dual wind turbines with shrouds as described in the first embodiment. To place a stack of up to ten FIG. 4 modules with turbines of only 100-foot diameter within the FIG. 7 support structure will produce a structure almost 2000 feet tall, which is beyond the reach of even the largest cranes. The FIG. 4 modules, 150 feet in diameter and 150 feet long need to be assembled in place because of their bulk and because their locations are inside the FIG. 7 support structure with no openings through which they can be inserted. Performance of this task requires a new method.

Yamamoto, U.S. Pat. No. 7,293,960, for example, teaches a floating wind generating facility that includes hexagonal shaped shrouds. The shape of the shrouds, and in particular the outer surfaces of the shrouds, has a shape that will create considerable drag.

Friesth, U.S. 2008/0124217, teaches a shroud that includes a planar face and non-aerodynamically shaped planer outer surface that together create substantial drag.

The facility taught in the present disclosure also includes a tower construction that may be extremely tall. In such a tall structure, it is important to minimize drag to prevent the tower from failing in extreme winds.

The prior art does team some substantial towers to optimize the capture of energy from the wind over a small square footage of foundation. Friesth teaches a tower construction that includes a core tower and a plurality of guys for providing lateral and torsional stability. Another example of a similar tower construction is shown in Weisbrich, U.S. Pat. No. 5,520,505.

The above-described references are hereby incorporated by reference in full.

SUMMARY OF THE INVENTION

The present invention teaches certain benefits in construction and use which give rise to the objectives described below.

The present invention provides a method for erecting a facility for producing electrical energy from wind, the method comprising the steps of preparing the site to receive the Facility, including constructing foundations; erecting the initial core tower panel and the initial peripheral tower sections on their respective foundations; installing work platforms; connecting and tensioning temporary guys between peripheral platforms and bases of adjacent peripheral towers; climbing all work platforms to a top of the core tower panel and tops of the peripheral tower sections; deploying tensioned temporary guys; lifting, positioning, and installing another core tower panel and other peripheral tower sections on top of the existing tower sections; concurrently climbing all work platforms to the top of the top core tower panel and the top of the top peripheral tower sections; repeating steps of installing panels until a desired height is reached; installing permanent guy pairs between the peripheral tower section and the base of each adjacent peripheral tower, and disconnecting temporary guys from the bases of the peripheral towers, and reconnecting and tensioning them at the middle of adjacent peripheral towers; assembling and temporarily engaging a truss and rail system at the base the core and peripheral towers, including lower rails; attaching a plurality of locked trucks to the lower inner and outer rails; attaching an upper frame to the plurality of trucks; assembling shroud sectors as needed to form shrouds; attaching the shrouds to upper and lower frames; repeating until a desired height is reached; repeating to complete an additional sector on each tower; repeating to complete additional shrouds; and repeating until the Facility is a desired height, and includes a desired number of shrouds.

A primary objective of the present invention is to provide a method of erecting a facility having advantages not taught by the prior art.

Other advantages of this method are as follows:

-   -   1. Many components used solely for erection are economical,         off-the-shelf items.     -   2. Components used solely for erection may be removed for re-use         on subsequent Wind Power System erection projects.     -   3. Workmen without specialized tower training or equipment can         do most of the structure erection work because work platforms         with suitable safety equipment are provided.     -   4. Workmen without specialized tower training or equipment can         do a significant amount of work at ground level.     -   5. Erection steps are sequenced so that erection and lifting         work on the structure and assembly work on the ground do not         occur concurrently, thus meeting the safety requirement of not         having work done overhead while men are working below. These         alternating steps can be done on different shifts, so the work         can proceed without delay.

Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The above-described drawing figures illustrate the invention, a method for erecting a facility for producing electrical energy from a prevailing wind above a surface.

The method of erecting the referenced first embodiment of the Wind Power System is comprised, first, of site preparation, second, of alternating among three erection sub-processes, and third, of removing special components. Erection sub-process one is a method of installing the tower portions of the support structure by adding increments to the top. Erection sub-process two is a method of assembling trusses and modules at the base of the facility. Erection sub-process three is a method of raising assembled trusses and modules while maintaining integrity of the supporting structure. When the erection sub-processes are complete, special components used solely for erection are removed for re-use.

First, we will discuss some of the structures of one embodiment of the invention. Then we will discuss the steps of construction used in one embodiment of the invention.

FIG. 1A is a perspective view of one embodiment of the facility. FIG. 1B is a perspective view of the facility of FIG. 1A, with a support structure removed to better illustrate multiple modules of the facility. The embodiment, singly or in multiple installations, is most efficient in meeting large power demands where construction sites are at a premium.

As illustrated in FIGS. 1A and 1B, the facility includes a power system, a plurality of shrouds, a plurality of wind turbines, a plurality of modules, a pivotal mounting system, and a support structure. The support structure supports a large number of the wind turbines far above the surface (e.g., ground, water, or other location) to both maximize the amount of wind captured, and also to minimize the footprint of the facility.

FIG. 2 shows a schematic view of one embodiment of the power system. The power system of FIG. 2 includes a wind turbine 204, a hydraulic system 206, an electrical generation system 208, struts 210, and a platform 212. The hydraulic system 206 may include a pump 214, a control system 216, motors 218, plus lines and other components 220. The hydraulic system 206 converts mechanical energy from the turbine 204, via the pump 214, to energy in the form of fluid flow. Fluid flow is then distributed to the appropriate hydraulic motors 218 by the controller 216. The hydraulic motors 218 then convert the fluid flow to mechanical energy which is transmitted to the generators 222.

The control system 216 of the power system includes distribution elements (e.g., valves) for distributing fluid flow from the pump to different size motors 218 and a logic to optimize the production of power. The control system 216 can also accept flows from a plurality of pumps 214 in the modules, illustrated in FIG. 4.

The turbine 204, the pump 214, and a portion of the lines and other components 220 are supported by the struts 210. The struts 210 are in turn supported by the shroud illustrated in FIG. 3A. The control system 216, motors 218, a portion of the electrical generation system 208, and a portion of the hydraulic lines and other components 220 are supported by the shroud, as discussed in greater detail below. While one embodiment of the power system is illustrated, alternative power systems known in the art (e.g., mechanical gearing, and other alternatives) may also be utilized, and such alternative embodiments should be considered within the scope of the present invention.

FIG. 3A shows one embodiment of one of the plurality of shrouds. As illustrated in FIG. 3A, the shroud is an aerodynamic hollow shell located around the wind turbine 204, as illustrated in FIG. 1A. The shroud of FIG. 3A may be a specially shaped toroid with a horizontal axis 324, an inner surface 304, and an outer surface 306. The shroud also has a front 308 and a rear 310. This front and rear orientation also applies to all components of the modules, illustrated in FIG. 4. Wind approaches the shroud from the front 308 and leaves the rear 310. The minimum diameter D of the inner surface 304 is the throat 312. The dimensions of the shroud and many other dimensions of the Wind Power System are proportional to the diameter D of the throat 312. As illustrated in FIG. 1A, the turbine 204 is located at the throat 312.

FIG. 3B illustrates a section from FIG. 3A shroud. The shroud of FIGS. 2A and 2B is a hollow shell of revolution, or toroid, formed by the path of FIG. 3B shape rotated a full circle of 360 degrees around the horizontal axis 324. FIG. 3B shape includes points 326, 328, 332, and 338, plus lines 330, 334, 336, and 340. The front 308 of the FIG. 3A shroud is more specifically defined as the circle generated by point 326 when FIG. 3B shape is rotated. Point 326 is located a distance of 0.7 D from the axis 324, but may be located in the range of 0.55 D to 0.95 D from axis 324. The rear 310 of the FIG. 3A shroud is more specifically defined as the circle generated by a point 328 when FIG. 3B shape is rotated. Point 328 is a horizontal distance of 1.5 D to the rear of the vertical plane containing point 326, but may be located in the range of 0.5 D to 2.5 D to the rear of point 326.

As illustrated in FIG. 3B, the outer surface 306 of the shroud of this embodiment includes an outer front curve 330 that begins at point 326 going away from and perpendicular to axis 324. The direction of curve 330 may vary as much as fifteen degrees to the rear of perpendicular to axis 324. Curve 330 terminates going parallel to and a distance of 0.75 D from axis 324 at point 332. The direction of curve 330 at its termination may vary as much as ten degrees away from parallel to axis 324. The distance of point 332 from axis 324 may vary from 0.6 D to 2 D. Point 332 is a horizontal distance of 0.075 D to the rear from point 326. Point 332 may vary from 0.05 D to 1.5 D to the rear from point 326. Curve 330 is a quadrant of an ellipse in the first embodiment, but may take any shape. The outer rear line 334 in FIG. 3B shape begins at point 332 and terminates at point 328. Line 334 varies in slope relative to axis 324 in the first embodiment. The minimum slope of line 334 is 4 degrees toward axis 324 at point 332 and the maximum slope is 6.5 degrees toward axis 324 at point 328. The slope of line 334 may vary from parallel to axis 324 to fifteen degrees toward axis 324.

As illustrated in FIG. 3B, the inner surface 304 includes an inner front curve 336 that begins at point 326 going toward and perpendicular to axis 324. The direction of curve 336 at its origin may vary as much as fifteen degrees to the rear of perpendicular to axis 324. Curve 336 terminates going parallel to and a distance of 0.5 D from axis 324 at point 338. The direction of curve 336 at its termination may vary as much as ten degrees away from parallel to axis 324. In the present embodiment, point 338 is a horizontal distance of 0.3 D to the rear from point 326. In alternative embodiments, point 338 may vary from 0.1 D to 1.5 D to the rear from point 326. Curve 336 is a quadrant of an ellipse in the first embodiment, but may be alternative shapes in different embodiments. The path of point 338, when rotated about the axis, forms the throat 312 of the shroud. The inner rear line 340 in the FIG. 3B shape begins at point 338 and terminates at point 328. Line 340 varies in slope relative to axis 324. The minimum slope of line 340 is 4 degrees away from axis 324 at point 338. The maximum slope of line 320 is 6.5 degrees away from axis 324 at point 328. The slope of line 340 may vary from zero degrees to fifteen degrees away from axis 324.

Shroud construction for this embodiment includes several additional provisions as follows: It provides for structural connection to the frame beams 502 and 522. It provides structural support for the struts 210 and the platform 212. It provides interior bracing, illustrated in FIG. 3E, as needed for structural stability and to facilitate assembly. In this embodiment, the shroud may be constructed to also include ingress (e.g., a door) to the interior of the shell. In this manner, the shroud may provide an interior work area as needed for maintenance of the power system. The interior work area may provide egress to service the turbine 204, and it may further provide interior lighting and a ventilation system for use when the interior is in use by maintenance personnel.

FIG. 3C is a perspective view of one embodiment of the platform 212 of the facility. FIG. 3D is a perspective cutaway of the shroud showing the platform of FIG. 3C positioned within the shroud of FIG. 3A. In the embodiment of FIGS. 3C and 3D, the platform 212 is positioned within the shroud and contains the control system 216, motors 218, a portion of the electrical generation system 208, and a portion of the hydraulic lines and other components 220. In this embodiment, the shroud serves the added purpose of containing and protecting the platform 212 and the above-mentioned components, and providing a safe location for maintenance workers to work on these components.

While the platform 212 may be internal to the shroud, it may also be located elsewhere if desired, or if the shroud is not big enough to accommodate it. The electrical generation system 208 includes direct current generators 222 increasing in size from small to large, module busses 224, a common direct current buss 226 and an optional alternating current electrical converter 228. The generators 222 and module busses 224 for each FIG. 4 module are located on the platform 212 for that FIG. 4 module. The common direct current buss 226 and optional alternating current converter 228 may be located at a base of the facility of FIG. 1A. The power system of FIG. 2 may produce direct current electricity, or alternating current electricity compatible to a power grid.

FIG. 3E is a front elevation sectional view of the shroud interior structure system 346. The shroud interior structure system 346 includes internal supports 350 between the inner surface 304 and the outer surface 306. While one arrangement of internal supports 350 is illustrated, alternative structures and arrangements may also be used, and such alternatives known in the art should be considered within the scope of the present invention.

FIG. 4 is an exploded perspective view of the module of FIG. 1A, and rails upon which the module is rotatably mounted. In the embodiment of FIG. 4, each module includes two shrouds (illustrated in FIG. 3A), and portions of the power system (illustrated in FIG. 2) located in the shrouds. In alternative embodiments, each module may include more than two shrouds, and the shrouds may be disposed in different arrangements (e.g., a pair of shrouds on either side, either side by side or stacked, or alternative numbers and arrangements of shrouds). Such alternatives should be considered within the scope of the present invention.

As illustrated in FIG. 4, each module may further include frames for connecting the shrouds. In the embodiment of FIG. 4, the frame may include an upper frame (illustrated in FIG. 5A), and a lower frame (illustrated in FIG. 5C). The upper frame of illustrated in FIG. 5A and the lower frame of FIG. 5C hold the shrouds in position and support them on opposite sides of the core tower, as illustrated in FIG. 1A.

As illustrated in FIGS. 4 and 5A, the upper frame includes frame upper beams 502 connected to the top of the shrouds at the front ends 504 and at the rear ends 506. Beams 502 are preferably directly above axis 324. Other convenient shroud load points 508 may also connected to the beams 502. The upper frame may further includes a front bar 512 between the two beam front ends 504, and a rear bar 514 between the two beam rear ends 506.

FIG. 5B is a detail of the outer truck 510. As illustrated in FIGS. 4 and 5B, the upper frame includes one or more mounted pairs of wheels, or trucks 510, attached above the four beam ends 504 and 506. These trucks 510 transmit the vertical loads from the module to the outer rail 704, as illustrated in FIG. 4. In the embodiment of FIGS. 4, 5A, and 5B, the pivotal mounting system includes the rails and trucks described herein. The pivotal mounting system may also include alternative embodiments known to those skilled in the art.

FIG. 5C illustrates one embodiment of the lower frame. In many respects the FIG. 5C lower frame is equivalent to the FIG. 5A upper frame, except it is turned upside-down to be located at the bottom of the FIG. 4 module rather than at the top. The specific differences of FIG. 5C lower frames from FIG. 5A upper frames are as follows: The shrouds of FIG. 3A are connected to the top of the beam ends 524 and beam ends 526 of the beams 522. Trucks 510 are attached to the bottom of the ends 524 and beam ends 526 of beams 522. Trucks 516 are attached to the bottom of the front bar 532 and to the bottom of the rear bar 534. Trucks 510 and trucks 516 are assembled with outer rails 704 and inner rails 706 located below.

As illustrated in FIG. 4, and FIGS. 5D and 5E, a plurality of trucks 516 are attached to the upper and lower frames for engaging the inner rails 706, for supporting horizontal loads placed upon the shrouds by the wind. FIG. 5D is a detail of the front inner truck. FIG. 5E is a detail of the rear inner truck. The trucks 516 are attached above the front bar 512, and may be centered on its mid-point; and the trucks 516 may also be attached above the rear bar 514, and likewise may be centered on its mid-point. These trucks 516 are positioned to transmit the horizontal load from the upper frame to the inner rail 706 (of FIG. 5E).

As illustrated in FIGS. 5A and 5C, truss members 518 transmit the upper frame horizontal loads from the beam 502 front ends 504 and rear ends 506 to the plurality of trucks 516 (as best illustrated in FIG. 4). These truss members 518 are arranged to provide a stable structure for transmitting the horizontal load from beams 502 to trucks 516. In the present embodiment, the upper frame members 502, 512, 514, and 518, except the trucks 510 and 516, are aligned on one horizontal plane.

As illustrated in FIG. 4, trucks 510 and 516 roll on circular rails 704 and 706, respectively, fixed to the structure illustrated in FIG. 7. The trucks 510 and 516, and rails 704 and 706, allow the module of FIG. 4 to rotate around the core tower (illustrated in FIG. 8). The trucks 510 and 516 are part of the frame of FIG. 5A The rails 704 and 706 are part of the structure of FIG. 7. The outer truck of FIG. 5B engages the outer rail 704. The inner trucks 516 engage the inner rails 706 in the front of the modules of FIG. 4. FIG. 5E shows the assembly of the inner trucks 516 with inner rails 706 above and to the rear of the modules of FIG. 4.

The module of FIG. 4 shows module guy pairs 402, which are pairs of cables connecting diagonally between the upper frame of FIG. 5A and the lower frame of FIG. 5C. One module guy pair 402 is located in a vertical plane at the front of the upper frame and the lower frame. Another guy pair 402 is located in a vertical plane at the rear of the upper frame and the lower frame. These module guy pairs 402 provide structural and dimensional stability to each module.

FIG. 6 is a schematic drawing of a module control system included in each of the modules of FIG. 4. The module control system includes a wind direction sensing device 604, a module control device 606, and a plurality of electric motors 608 for driving a plurality of outer trucks 510. The module control system is installed in each module to keep it positioned facing the prevailing wind. When the wind direction sensing device 604 senses a change in the direction of the wind, using technology known to those skilled in the art, the module control device 606 uses the electric motors 608 to turn the module in a manner that maintains the module in the correct orientation with respect to the wind.

FIG. 7 shows a top plan view of one embodiment of the support structure. The support structure of this embodiment includes a core tower illustrated in FIG. 8, peripheral towers illustrated in FIG. 9, the truss and rail system described above, and guys 702. In this embodiment there are six peripheral towers; however, this number may vary depending upon the requirements of those skilled in the art (three or greater may be used).

As illustrated in FIG. 10, the truss and rail system includes a ring truss (illustrated in FIG. 11), six radial trusses (illustrated in FIG. 12), six peripheral trusses (illustrated in FIG. 13), six rail trusses (illustrated in FIG. 14), one or two outer rails 704, one or two inner rails 706, and 12 or 24 braces 708. The number of FIG. 12 radial trusses, FIG. 13 peripheral trusses, FIG. 14 rail trusses, and braces 708 will change in correlation with the number of FIG. 9 peripheral towers used.

The FIG. 10 truss and rail system connects the FIG. 8 core tower to the FIG. 11 ring truss and connects the FIG. 11 ring truss to the FIG. 9 peripheral towers by means of the FIG. 11 radial truss. The FIG. 10 truss and rail system connects adjacent FIG. 9 peripheral towers to one another by means of the FIG. 12 peripheral trusses. The FIG. 10 truss and rail system connects adjacent FIG. 11 radial trusses to one another by means of the FIG. 13 rail trusses. Each FIG. 10 truss and rail system comprises one or two outer rails 704 and one or two inner rails 706. Outer rails 704 and inner rails 706 are provided as needed to receive vertical and horizontal loads respectively from outer trucks 510 and inner trucks 516 of the FIG. 4 modules. Braces 708 provide supplemental lateral support to inner rails 706 by connecting them to FIG. 11 ring trusses. FIG. 10 truss and rail systems occur at vertical intervals sufficient to allow the FIG. 4 modules to be supported between them. Individual FIG. 4 modules may be omitted at the discretion of the owner and the space left empty or used for other purposes. The FIG. 10 truss and rail system locations are above, between and below the FIG. 4 modules.

FIG. 8 shows the first embodiment of the core tower. The FIG. 8 core tower has three vertical legs 802 forming an equilateral triangle. The legs 802 are separated by a horizontal distance of 0.433 D identified as a face 804 of the FIG. 8 core tower. The number of legs in the core tower may also be four, and the distance between legs may vary from 0.1 D to 0.7 D. Each of the three faces 804 has a pattern of lacings 806 between the legs 802. This lacing pattern is repeated at intervals, which intervals are the definition of a panel 808 of the FIG. 8 core tower. A sector 810 of the FIG. 8 core tower is defined as enough panels connected into a vertical stack to equal the vertical distance between the centerlines of FIG. 10 truss and rail systems. FIG. 11 ring trusses are attached at the middle of the top panel 808 of each sector 810. The legs 802 of the top panel 808 of each sector 810 are strengthened to support the attached FIG. 11 ring truss. The bottom of each leg 802 is supported by a foundation 812 which may be any configuration appropriate for the soils at a specific site and the loads imposed.

FIG. 9 shows the first embodiment of the peripheral tower. The FIG. 9 peripheral tower has three vertical legs 902 forming an equilateral triangle. FIG. 9 peripheral tower may also be configured to have four legs. One of the legs 902 is oriented toward the center of the FIG. 8. core tower. Legs 902 are separated by a horizontal distance of approximately 0.10 D, which is identified as a face 904 of the FIG. 9 peripheral tower. The face width may vary from 0.05 D to 0.25 D. Each of the three faces 904 has a pattern of lacings 906 between the legs 902. This lacing pattern is repeated a sufficient number of times to equal the panel 808 height of the FIG. 8 core tower. This panel height is the definition of a section 908 of the FIG. 9 peripheral tower. A sector 910 of the FIG. 9 peripheral tower is defined as enough sections 908 connected into a vertical stack to equal the vertical distance between the centerlines of FIG. 10 truss and rail systems. FIG. 12 radial trusses and FIG. 13 peripheral trusses are attached at the middle of the top section 908 of each sector 910. The legs 902 of the top section 908 of each sector 910 are strengthened to support the attached FIG. 12 radial truss and FIG. 13 peripheral trusses. The bottom of each leg 902 is supported by a foundation 912 configured appropriately for the soils at each site and the loads imposed.

FIG. 11 shows the first embodiment of ring truss. FIG. 11 ring trusses include a top ring 1102 and a bottom ring 1104. Each ring 1102 and ring 1104 includes six equal members 1106. If more or less than six FIG. 9 peripheral towers are used, the number of members in the ring 1102 and ring 1104 are modified to match. The lengths of the sides of the FIG. 11 ring truss are sufficient for it to span around FIG. 8 core tower and connect to the FIG. 8 core tower legs 802. The vertical distance between rings 1002 and 1004 is 0.1167 D, but may vary from 0.05 D to 2.5 D. Each corner of the top ring 1102 is connected to the corner of the bottom ring 1104 directly below with a vertical strut 1108. Each portion of the FIG. 11 ring truss between adjacent struts 1108 is defined as a face 1110 of the FIG. 11 ring truss. Each of the faces 1110 has a pattern of lacings 1112 between the adjacent struts 1108 to provide structural stability to the frame. Each FIG. 11 ring truss is positioned around the FIG. 8 core tower so some of its corners align vertically with the legs 802 of the FIG. 8 core tower.

OPERATION OF THE FIRST EMBODIMENT

Each FIG. 4 module is continually oriented to face directly into the prevailing wind. The wind entering the front 308 of each FIG. 3A shroud has its velocity increased by approximately 50 percent at the throat 312 by the carefully selected aerodynamic shape of the outer front curve 330 and the inner front curve 336. This increased wind velocity then drives the turbine 204 located at the throat 312 and the related FIG. 2 power system to produce electric energy for human use. Both the FIG. 3A shroud shape and the FIG. 2 power system are selected and optimized to increase the power production as much as possible

The wind passing over the FIG. 3A shroud produces drag forces. The total aerodynamic shape of the FIG. 3A shroud is optimized to the extent feasible to reduce these drag forces. This is significant because all structural components of the Wind Power System must provide the strength to resist wind forces as well as support the weight of the System. The cost of this strength affects the commercial feasibility of the System.
